Peach, Luigi

Pikachu, Toon Link, and Mega Man. I'll also try Pac Man and Greninja.

I dunno. It depends on how the new characters play. My mains in last game were Zero Suit and Pokemon Trainer so I'll try them out first. I'm a huge Mega Man fan, but I usually don't like projectile based fighting characters. Robin looks interesting, as does Wii Fit Trainer. Plus I've always liked Bowser who seems better this time around.

If Ike controls similar to his Wii counterpart, I'm probably gonna choose him.

Ike for sure. I'll be trying out Greninja, Robin, Shulk, and Link as well.

I tend to play as Olimar, Sonic, Jigglypufg, Ness/Lucas and Ike a lot nowadays so I'll keep with them. I'm interested in the dog and Robin too.

I really want to like Villager but I would have to play as him first to see if I could actually use him well. His move set is a bit weird.

Who ever you guys main, i'll be sure to kick their A$$ XD

Seriously though, Rosalina+Mario and many others :)

My original main was Pikachu. Since Melee it has been Zelda and occasionally Peach. This time though....damn! There are a good 15-20 characters that genuinely interest me, and I could see myself sticking with half a dozen or more of them.
